QPR look safe - they only need 2 wins and a draw. Agree with you on Wigan though, they need 3 wins and a draw to be certain, but have Reading, Burnley and Blackburn still to play.
Talking of Blackburn, don't rule them out. Just 2 points behind us, their run-in list looks kind:
Sheff Wed V...
If Bournemouth do us a favour and get something against Reading, and we do the near-impossible and beat Leicester, you really shouldn't rule us out because we have the ideal run-in. (Even playing Forest away could play into our hands)
